FIELD OF THE INVENTION

[0001] The present invention relates to an ink used for an ink jet printer in which at least a portion of a member being in contact with the ink is formed by a glass, particularly any one of a borosilicate glass, a soda lime glass, a photosensitive glass, single crystal silicon, polysilicon, a silicon oxide film, a titanium nitride film, a zirconium film, a titanium oxide film, and a silicon nitride film; and an ink jet recording method, an ink cartridge and an ink jet recording apparatus.

BACKGROUND OF THE INVENTION

[0002] An ink jet recording system has been recently spread abruptly because of advantages that a main body is small, low price, and low running cost. Accordingly, an ink jet printer capable of printing on non coated papers such as a transcription paper for electrophotography, a printing blank, a typewriter blank, a wire dot printer blank, a word processor blank, a letter blank, a report blank and the like is also put into the market.

[0003] There is an ink jet printer in which a glass, or silicon and silicon oxide on the glass is further used from the viewpoints of easy fine processing, processing precision, and the like, among ink jet printers.

[0004] An ink used for such ink jet printer is usually composed of a coloring agent which is dissolved or dispersed in a solvent and a wetting agent; a polyhydric alcohol or ethers thereof with a solvent, and according to requirement, contains a penetrant, a fungicide, a preservative, a dispersant and the like. However, when the ink is filled up in the above-mentioned ink jet printer in which a glass, or silicon and silicon oxide on the glass was further used and used or left alone for long time, a glass, or further silicon and silicon oxide which are in contact with the ink is eluted.

[0005] Accordingly, the design precision of the ink jet printer is lost, the size of ink drops and the discharge speed of the ink drops are changed, the quality of an image is lowered, and discharge inferiority occurs in the worst case. A conjunction strength is lowered caused by the elution of a glass or further silicon and silicon oxide at a conjunction part, the discharge inferiority occurs, and the conjunction part is peeled out in the worst case to be troubled. In particular, in case of an ink jet printer in which a liquid chamber part is composed of a glass or silicon and silicon oxide, since the dimension precision of the liquid chamber part which requires precision is lowered, the above-mentioned problems occur remarkably.

[0006] Further, in case of an ink jet printer in which a fluid resistance is composed of a glass or silicon and silicon oxide, the fluid resistance is lowered because of the elution of a glass or further silicon and silicon oxide. Accordingly, the size of ink drops and the discharge speed of the ink drops are remarkably changed, the quality of an image is lowered, and the discharge inferiority occurs in the worst case.

[0007] Further, in case of an ink jet printer in which a vibration plate is composed of a glass or silicon and silicon oxide, the thickness of the vibration plate is lowered. Accordingly, the size of ink drops and the discharge speed of the ink drops are changed, the discharge inferiority occurs, the quality of an image is lowered, and the vibration plate is finally made thin and destroyed without enduring vibration.

[0008] Further, in case of an ink jet printer in which a nozzle is composed of a glass or silicon and silicon oxide, since the diameter of the nozzle is enlarged, the size of ink drops and the discharge speed of the ink drops are changed, the discharge inferiority occurs, and the quality of an image is lowered.

[0009] On the other hand, in case of an ink in which a glass or silicon and silicon oxide was eluted, the solubility or dispersibility of a coloring agent is lowered, and the clogging and the like caused by the precipitation of the coloring agent are provoked. Further, the glass or silicon and silicon oxide itself which was eluted reaches a supersaturated state because of evaporation of a solvent such as water or the like, is precipitated at a nozzle surface and the like, and clogging is provoked. Since these problems are not solved at status quo, for example, a head is also simultaneously exchanged when an ink which was preliminarily filled up was exhausted, and the like, and it was used only for comparatively short period.

[0010] As ink jet printers for solving these problems, there is a method of prevention by providing a layer of an organic material and an inorganic material such as SiN, TiN, TiO or the like on a glass or silicon and silicon oxide, as described in Japanese Patent Application Laid-open Publications Hei No. 5-155023, WO98-42513 and the like. This method has an effect of preventing the elution of a glass or silicon and silicon oxide, but since production steps are increased, it needs a robust cost, and causes a very precious ink jet printer. Further, these films tend to generate pinholes, it is difficult to uniformly form the film, and defects occur often. Further, according to the system and structure of the head, there is occasionally a case of being unable to take the formation of the film itself in steps. Further, according to a recent experiment, even if these layers are provided, it has been clarified that a certain dye of a black dye cannot prevent the elution, and it is also confirmed that the elution exceeding the specification value occurs in other coloring agents.

[0011] There is proposed a method of preventing the elution by adding urea in an ink and dissolving stably a glass or silicon and silicon oxide in the ink even if it is eluted, as the ink in Japanese Patent Application Laid-open Publications Hei No. 9-123437. However, since even this method does not prevent the elution of a glass or silicon and silicon oxide it self, it cannot be applied to a part to which precision is required.

[0012] Accordingly, required is an ink, which is not eluted even on a substrate, in which a layer of silicon oxide whose film can be comparatively easily formed by a glass or silicon and silicon oxide, and further by an organic material and an inorganic material such as SiN, TiN, TiO or the like is provided on a glass or silicon and silicon oxide.

[0013] An ink in which the content of sodium ion is prescribed is described in Japanese Patent Application Publications Hei No. 7-51687. Further, the contents of sodium ion and potassium ion are prescribed in Japanese Patent Application Laid-open Publications Hei No. 5-331391, and similarly, inks in which the contents of sodium ion and potassium ion are respectively prescribed are described in Japanese Patent Application Laid-open Publications No. 333542 and No. 9-25441.

[0014] Further, the present inventor proposes an ink which contains a specific dye and a quaternary ammonium as its counter ion in the ink in Japanese Patent No. 1677642, and proposes an ink which contains a dye and a quaternary phosphonium ion in the ink in Japanese Patent No. 2085163. These are technologies which were proposed for clogging, cogation, preservation stability and the like. Accordingly, they are not those which were adequately studied about the prevention of the elution of a glass or silicon and silicon oxide being in contact with an ink, and further, about the prevention of the elution of a substrate in which an organic material and an inorganic material such as SiN, TiN, TiO or the like is provided on a glass or silicon and silicon oxide. In fact, even if these inks are used, the problem of the elution of glass or silicon and silicon oxide could not be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0071] The present invention is illustrated in detail below.

[0072] The present inventors obtained a conception that the total of the content of all alkali metals which are contained in an ink is about 800 ppm from a measurement result of ICP, but since 0.05% to 5.0%, preferably 0.1% to 2.0% and more preferably 0.2% to 0.8% of a corrosion inhibitor is contained, the elution of a glass or silicon and silicon oxide being in contact with an ink can be prevented. The corrosion inhibitor mentioned here means a phosphonium ion, an olefin-based compound, a cationic resin, a cationic surfactant, a cationic coloring agent and the like.

[0073] Further, the alkali metal mentioned here is a metal of Group I of the Periodic Table, and specificarylithium, sodium, potassium rubidium, cesium and francium. Further, in the actual ink, amount of sodium is the greatest. Further, francium exists at an amount of several hundred grams in 20 km of the earth crust on the Earth by calculation, exists very rarely on the Earth, therefore its amount may be considered to be nearly zero gram. Accordingly, the total content of alkali metals can be regulated without considering the amount of francium.

[0074] As the glass used in the present invention, any usual glass may be used. A borosilicate glass, a quartz glass, a low alkali glass, a non-alkali glass and a soft glass (blue glass) are preferably mentioned. When it is used for a head which is composed of the glass in combination with other material, it is preferable to use glasses having an approximate linear expansion coefficient, and for example, in case of a head constituted with silicon, Pyrex glass # 7740, Corning Coat 7913, Corning Coat 7052, Corning Coat 7056 and the like are mentioned. As the glass being most preferable for anode conjunction, non alkali glass substrates OA-2 and OA-10, a low alkali glass substrate BLC (Nippon Electric Glass Co., Ltd.), blue glasses (soft glass) SL and NA (HOYA), and the like are mentioned. These glasses can be connected with silicon.

[0075] Further, a photosensitive glass can be also used. The photosensitive glass in which anisotropic etching can be carried out is more preferable. Specifically, photosensitive glass manufactured by HOYA Co., Ltd. and Nippon Electric Glass Co., Ltd. in which anisotropic etching can be carried out can be used.

[0076] Since the alkali metal in an ink invades into a glass, or further silicon, silicon oxide and the like which are in contact with the ink to be dispersed, it is considered that it has an action of continuously eluting the glass, silicon and the like. The elution of silicon and silicon oxide can be also suppressed by setting the total content of alkali metals in the ink as 700 ppm or less, preferably 150 ppm or less, and further preferably 50 ppm or less. The elution can be also suppressed to a level which may be out of consideration by containing the corrosion inhibitors such as a phosphonium ion represented by the general formula (Formula 1) a phosphonium ion represented by the general formula (Formula 1) and the like, without reducing the content of alkali metals. As its reason, the corrosion inhibitors are adsorbed on silicon, silicon oxide and the like which are in contact with the ink, to be remained, the glass and silicon are not continuously eluted, and it is considered that they have an action of preventing the elution of the glass and silicon even if the content of alkali metals is much. This can be confirmed by the difference of zeta electric potential in comparison with no addition of the corrosion inhibitors, examining an electric double layer when they were added, and it can be confirmed that they are adsorbed on the surfaces of the glass and silicon to be remained.

[0077] Further, since 30% or more of a quaternary ammonium ion and an alkanolamino ion which are indicated by the formula A of the 50% or more, based on the equivalent of an anionic compound which is in contact with the ink is contained, the elution of the glass and silicon being in contact with can be further suppressed. Since the quaternary ammonium ion and the alkanolamino ion which are indicated by the formula A are adsorbed on the surface of the glass, silicon, and silicon oxide being in contact with the ink to be remained, the continuous elution in the glass, silicon, and silicon oxide is not carried out, and it is considered that they have an action of preventing the elution.

[0078] Further, in the present invention, the ion is not always one kind of compound, and a mixture with other ions and compounds can be used. The ions include a sulfonium ion, an ammonium ion, a phosphonium ion, an arsonium ion and the like. The compounds include a cationic resin, a boron compound, an olefin-based compound and the like. Among the phosphonium ion represented by the general formula (Formula 1), the compounds indicated the under-mentioned formulae (Chemical Formula 1), (Chemical Formula 2), (Chemical Formula 3) and (Chemical Formula 4) have a high prevention effect of the elution of the glass, silicon, and silicon oxide in particular, are superior in the dispesribility and dissolution stability of the coloring agent, and other qualities required for the ink for ink jet recording are satisfied, therefore they are further preferable.

[0079] As the phosphonium ion represented by the general formula (Formula 1) other than the compounds indicated the above-mentioned formulae (Chemical Formula 1), (Chemical formula 2), (Chemical Formula 3) and (Chemical Formula 4), specifically, the compounds indicated the under-mentioned formulae (Chemical Formula 5) to (Chemical Formula 26) can be mentioned.

[0080] Further, in the present invention, it is unnecessary that all of the ions are the compound of the above-mentioned formula A, and can be mixed with other ions.

[0081] Among the quaternary ammonium ion and the alkanolamino ion which are indicated by the formula A, corrin indicated by the formula B, triethanol amine indicated by the formula C, tetramethylammonium indicated by the formula D and ammonium ion indicated by the formula E have particularly high prevention effect of the elution of silicon and silicon oxide, are superior in the dispersibility and dissolution stability of the coloring agent, and other qualities required for the ink for ink jet recording are satisfied, therefore they are further preferable.

[0082] As the quaternary ammonium ion and the alkanolamino ion which are indicated by the formula A other than corrin, triethanol amine, tetramethylammonium and ammonium ion, those shown below can be mentioned.

[0083] It is needless to say that they are not limited to these. Among these, one kind or a plurality of kinds can be added if they are within a range of satisfying other quality which is required for the ink for ink jet recording and having no side reaction such as toxicity or the like. Among these, carbon numbers of 4 to 12 in a molecular ion is preferable. When the carbon numbers is greater than 12, the solubility in a solvent such as water or the like is lowered, and there tend to occur side effects that clogging occurs during the stop of printing and during continuous printing, and the separation of an ink and the occurrence of precipitation tend to occur.

[0084] The present invention can prevent corrosion even if the content of alkali metals is much as described above, and further, the present invention prescribes the content of alkali metals as described above. However, when the anionic compounds such as a coloring agent, a penetrant, a dispersant, a surfactant and the like are obtained by the form of alkali metal salts such as a sodium salt, a potassium salt and the like, the content of alkali metals occasionally exceeds the prescribed amount of 800 ppm when they are used according to an addition amount as they are. In this case, at least a portion of the counter ion of alkali metals is replaced with ions other than alkali metal salts, and thus the content of alkali metals may be reduced.

[0085] As the method, a method by an ion exchange resin, and a method of a salt precipitation method of adding a desired ion, preferably a salt containing an onium ion which is indicated by the general formula (Formula 1) and the general formula (Formula 2) to a solution of alkali metals such ac sodium and the like, or adding a salt which contains the quaternary ammonium ion and the alkanolamino ion which are indicated by the formula A to precipitate, are mentioned as a method of directly exchanging ions. As a method of converting a salt of alkali metals such as sodium and the like to a free acid once, a method of adding a strong acid to the anionic compound or its solution and separating it by solvent extraction, residue, filtration and the like is mentioned in addition to the method of treating with the ion exchange resin.

[0086] When the anionic compound is obtained in a form other than alkali metals, it may be used as it is. Further, at least a portion of ions may be used in place of the phosphonium ion indicated by the general formula (Formula 1), or in place of the quaternary ammonium ion and the alkanolamino ion which are indicated by the formula A.

[0087] When the anionic compound is obtained in a form of a free acid, the ink of the present invention can be also obtained by adding an ion other than alkali metals, preferably the phosphonium ion indicated by the general formula (Formula 1) in place of at least a portion of the anionic compound of a free acid or its solution, or an ion other than alkali metals, preferably the quaternary ammonium ion and the alkanolamino ion which are indicated by the formula A in place of at least a portion of the anionic compound of a free acid or its solution.

[0088] Specifically, there is a method described below for adding the phosphonium ion to the ink composition.

[0089] (i) Method of Adding as pH Adjusting Agent

[0090] The phosphonium ion can be added to the ink composition by adding phosphonium hydroxide, phosphonium carbonate and the like as a pH adjusting agent. Namely, phosphonium hydroxide, phosphonium carbonate and the like have about the same acid-base dissociation constant as sodium hydroxide, sodium carbonate and the like, and the addition can be carried out using phosphonium in similar manner as that pH of an ink was conventionally adjusted using sodium hydroxide, sodium carbonate and the like.

[0091] (ii) Method of Adding as Counter Ion of Dye

[0092] There is the following method as a method of adding as the counter ion of a dye which has an acidic group such as —SO₃H, —COOH, —OH or the like.

[0093] (a) Acid Precipitation Method

[0094] The method can be used when a dye is precipitated when the pH value of its solution is lowered.

[0095] A dye [DM] which is a salt of a cation (generally, Na⁺) other than phosphonium is dissolved in a solvent, an acid such as hydrochloric acid, sulfuric acid, acetic acid, nitric acid or the like is added thereto, and the dye which is a form of a free acid is precipitated.

[0096] D⁻M⁺+H⁺X⁻→DH↓+M⁺X⁻

[0097] (D dye ion, M . . . cation such as Na, NH₄, K or the like, X . . . Cl⁻, NO³⁻, so²⁻ ₄, CH₃COO⁻ and the like)

[0098] A precipitate is filtrated and washed, and M⁺X⁻ as impurities is removed. The dye thus obtained is dissolved by phosphonium hydroxide to be used for an ink.

[0099] DH⁺[R₁R₂R₃R₄P]⁺OH⁻→D⁻[R₁R₂R₃R₄P]⁺+H₂₀

[0100] (b) Salt Precipitation Method

[0101] A dye is dissolved in a water-ethanol mixed solvent, a water-methanol mixed solvent or a water-acetone mixed solvent, a phosphonium salt such as phosphonium chloride, phosphonium acetate, phosphonium sulfate or the like, and the dye is precipitated as a phosphonium salt.

[0102] D⁻M⁺+[R₁R₂R₃R₄P]⁺X⁻→D[R₁R₂R₃R₄P]↓+M⁺X⁻

[0103] The precipitate obtained is filtrated, washed with the solvent, and M⁺X⁻ is removed. The dye can be used as an ink as it is.

[0104] (c) Ion Exchange Method

[0105] A resin or a membrane which has the capability of ion exchange is used, a dye solution is directly converted to a phosphonium salt by being passed through the resin or the membrane, and after converting once to the form of a free acid in like manner as in the acid precipitation method, the phosphonium salt of the dye is obtained by phosphonium hydroxide.

[0106] A) The ion of an ion exchange group is converted to a phosphonium type, and passed through the dye solution.

[0107] R⁻[R₁R₂R₃R₄P]⁺+D⁻M⁺→R⁻M⁺+D⁻[R₁R₂R₃R₄P]+

[0108] (R⁻ is the ion exchange group of an ion exchange resin or a membrane)

[0109] B) The ion exchange group is converted to a H type and passed through the dye solution. In this case, it is suitable for the ion exchange of an acidic dye which has the high solubility of a free acid type dye, in particular.

[0110] R⁻H⁺+D⁻M⁺→D⁻H⁺+R⁻M⁺

[0111] (d) Method of Adding Phosphonium Salt at Synthesis Step

[0112] A phosphonium salt is used for a material at synthesizing a dye. For example, when an acidic compound in a raw material is dissolved and added, it is conventionally dissolved using sodium hydroxide, but it is a method of dissolving using a phosphonium salt at this time. [R₁R₂R₃R₄P]⁺NO₂ is used in place of NaNO₂ which is used for diazotization. NaOH and Na₂CO₃ have been conventionally added in the reaction solution in order to carry out alkali coupling, but a method of adding a phosphonium salt in place of this and the like are mentioned.

[0113] (e) Extraction Method

[0114] It is a method of utilizing to an ink D⁻[R₁R₂R₃R₄P]⁺ obtained by utilizing the solubility difference of D⁻M⁺ and D⁻[R₁R₂R₃R₄P]⁺ or D⁻H⁺ to a specific solvent. For example, obtained is a method that after a dye of D⁻M⁺ is dissolved, a phosphonium salt is added, the solvent in the solution is evaporated to be dried, a mixture of the phosphonium salt of the dye and an M⁺ salt was obtained, then Soxhlet extraction is carried out, and the phosphonium salt of the dye having high solubility in methanol is obtained.

[0115] (iii) Method of Adding as Counter Ion of Additive to Ink Other than Dye

[0116] Electroconductive adjusting agent . . . NaCl, LiCl, Na₂SO₄, and NaNO₃ and the like have been conventionally used, but the phosphonium salt can be used in place of these.

[0117] Preservative . . . sodium dehydroacetate, sodium benzoate, sodium salt of 2-pyridynethiol oxide, sodium salt of 1,2-benzi-isothiazaline-3-one and the like are used, but the phosphonium salt is used in place of these sodium salts.

[0118] Surfactant . . . The phosphonium salt is used in place of the sodium of an anion surfactant such as sodium dodecylbenzenesulfonate or the like.

[0119] Chelating agent . . . The phosphonium salt is used in place of the trisodium salt of EDTA.

[0120] It is most preferable to add as phosphonium hydroxide or phosphonium carbonate as an adjusting agent of pH value, or add as the counter ion of a dye including an acidic group such as a sulfonic acid, a carboxylic acid or the like, in order to add the phosphonium salt to the ink composition. Even if it is used as a pH value adjusting agent, or even if it is used as the counter ion of the raw material of an ink of other dye or the like, almost all of the phosphonium ions are dissociated to exist as [R₁R₂R₃R₄P]⁺, and the cation in the ink usually exist most as the counter ion of an ink from the point of quantity.

[0121] The lesser the ions such as Na⁺, K⁺, NH₄ ⁺, and the like other than the phosphonium which is contained in the ink are, the larger the effect of the present invention is, therefore it is preferable to use the counter ion (cation) of an ink in place of the phosphonium by any one of the above-mentioned methods or other methods, according to the object.

[0122] Thus, when the anionic compound can be obtained in the form of a free acid, it is unnecessary to convert a free acid type compound to a salt other than alkali metals at preparation of the ink. The anionic compound having the above-mentioned counter cation is contained in the ink, by adding 30% or more and more preferably 50% or more of a phosphonium ion represented by the general formula (Formula 1a) based on the equivalent of an anionic compound and adjusting the pH value of the ink at 6.0 or more, or by adding in a free acid type anionic compound 30% or more and more preferably 50% or more of a quaternary ammonium ion and an alkanolamino ion which are indicated by the formula A, based on the equivalent of an ion other than alkali metals, preferably the free acid type anionic compound in the ink and adjusting the pH value of the ink at 6.0 or more. Accordingly, the work required for production of the ink becomes simple in particular, and further, it is preferable to be able to very easily prevent the elution of a glass, silicon, silicon oxide and the like.

[0123] When the counter ion is the phosphonium ion represented by the general formula (Formula 1), it is preferable that carbon number in a molecule is 4 to 12. Alternatively, when the counter ion is the quaternary ammonium ion and an alkanolamino ion which are indicated by the formula A, it is preferable that it has a substituted or non-substituted alkyl group and the carbon number in a molecule is 4 to 12. When the carbon number is bigger than 12, the solubility to a solvent such as water or the like is lowered, and there tend to occur side effects that clogging occurs during the stop of printing and during continuous printing, and the separation of an ink and the occurrence of precipitation tend to occur.

[0124] Counter Ion of Onium Salt:

[0125] X may be arbitrarily a halogen ion; an inorganic anion such as a nitric acid ion, a nitrous acid ion, an acetic acid ion, a phosphoric acid ion, a sulfuric acid ion or the like; an organic anion and the like which were derived from an organic acid such as formic acid, acetic acid, propionic acid, butyric acid, valeric acid, glycolic acid, gluconic acid, a lactic acid, and the like. Among these, it is preferable that it is ionically dissociated in the ink at a high rate. Accordingly, a mono-valent ion selected from a halogen ion, a nitric acid ion, a nitrous acid ion and an acetic acid ion is preferable, and a hydroxyl ion is preferable in particular.

[0126] In addition to the phosphonium ion, the similar effect is observed by adding about 1% of a usual cationic resin such as a polyarylamine, a polyethyleneimine or the like. Further, OLFIN B and P, SURFYNOL 61 and the like of an acetylene surfactant which has a cylindrical electronic cloud (π-electron) of a triple bond and an active hydrogen atom of an adjacent OH group prepare orientation and complex formation on the surface of a glass and silicon easily, and reveal the similar effect as the phosphonium ion. Further, a cationic dye, a cationic carbon black and a cationic pigment orient on the surface of a glass and silicon, and reveal the similar effect as the phosphonium ion.

[0131] Further, when the coloring material that is an inclusion compound included by a resin or a colored resin fine particle which was colored by the coloring material, the elution of a glass and silicon can be reduced. The reason is considered that in case of impurities in the coloring material, particularly a carbon black, an acidic component which is contained in the carbon black dissolves the glass and silicon, and considered that the action of the component can be reduced by packing with a resin or forming a fine particle with the resin. Specifically, there are a micro-capsulated carbon black manufactured by Dainippon Ink and Chemicals, Inc., a micro-capsulated carbon black manufactured by Toyo Ink Mfg. Co., Ltd., a resin particle manufactured by Toyobo Co., Ltd., an emulsion ink of a dye and pigment manufactured by Kao Corporation and the like.

[0187] The ink jet recording apparatus equipped with the recording liquid storing part which stores the recording liquid of the present invention and the recording unit having heads for discharging the recording liquid is illustrated referring to the drawings. Further, example mentioned below are only one of configuration examples, and does not limit the present invention at all.

[0188]FIG. 1 is a schematic frontal view of the mechanism part of a serial type ink jet recording apparatus which mounts an ink cartridge equipped with the recording liquid storing part which stored the recording liquid of the present invention. The mechanism part of a serial type ink jet recording apparatus horizontally constructs the main supporting guide rod (3) and the sub supporting guide rod (4) between the side boards (1) and (2) of both sides at an about horizontally positional relation, and the carriage unit (5) is supported by the main supporting guide rod (3) and the sub supporting guide rod (4) in a condition in which it can be freely slid to a main scanning direction. The respective four heads (6) which respectively discharge a yellow (Y) ink, a magenta (M) ink, a cyan (C) ink, and a black (Bk) ink are mounted in the carriage unit (5), facing the discharge face (nozzle face) (6 a) downward. Further, four ink cartridges (7 y), (7 m), (7 c) and (7 k) which are the ink feeding bodies of the respective colors for feeding the respective inks to the four heads (6) are exchangeably mounted on the upper side of the heads (6) of the carriage unit (5).

[0189] Then, the carriage unit (5) is linked with the timing belt (11) which was tensed between the drive pulley (drive timing pulley) (9) which is rotated by the main scanning motor (8) and the idler pulley (10), and the carriage unit (5), namely the four heads (6) are designed to be moved to the main scanning direction by controlling the drive of the main scanning motor (8). Further, the sub frames (13) and (14) are provided on the bottom board (12) which connects the side boards (1) and (2), and retain the delivery roller (15) for feeding the blank (16) between the sub frames (13) and (14) to a vice scanning direction which is orthogonalized against the main scanning direction. Further, the vice scanning motor (17) is arranged at the sub frame (14) side, and the gear (18) which was fixed on the rotational shaft of the vice scanning motor (17) and the gear (19) which was fixed on the rotational shaft of the delivery roller (15) are provided for transmitting the rotation of the vice scanning motor (17) to the delivery roller (15).

[0190] The reliability restoration mechanism (21) (hereinafter, referred to as “sub system”) of the heads (6) is arranged between the side board (1) and the sub frame (13). The sub system (21) retains the four cap procedure (22) which caps the discharge faces of the respective heads (6), by the holder (23). The holder (23) is retained by the link member (24) in a condition in which it can be swung. The carriage unit (5) hits the hooking part (25) which was provided at the holder (23), by the movement of the carriage unit (5) to the main scanning direction. Thus, the holder (23) is lifted up in accordance with the movement of the carriage unit (5), and the discharge faces (6 a) of the ink jet heads (6) are capped by the four cap procedures (22). When the carriage unit (5) moves to the printing region side, the holder (23) is lifted down in accordance with the movement of the carriage unit (5). Thus, the four cap procedures (22) leave the discharge faces (6 a) of the ink jet heads (6).

[0191] Further, the four cap procedures (22) are respectively connected with the suction pumps (27) through the suction tubes (26), form the atmosphere release orifice (47), and connected with air through the air release tubes (26) and the air release valves. Further, the suction pumps (27) discharge waste liquid which was sucked, in a waste liquid storing vessel which is not illustrated, through drain tubes and the like. Further, the wiper blade (28) which is a wiping procedure consisting of an elastic member which is made of a fiber member, a foaming member or a rubber for wiping the discharge faces (6 a) of the ink jet heads (6), is installed on the blade arm (29). The blade arm (29) is supported by a shaft in a condition in which it can be swung, and swung by the rotation of the cam which is rotated by a rotational procedure not illustrated.

[0192] Then, the ink cartridges (7) are illustrated referring to FIG. 2 and FIG. 3. FIG. 2 is a cross-eyed appearance view of the ink cartridges before being mounted on the recording apparatus. FIG. 3 is a frontal section view of the ink cartridge. As shown in FIG. 3, the ink cartridges (7) store the ink absorber (42) which absorbed requisite color inks in the cartridge main body (41). The cartridge main body (41) is formed by adhering or melt-adhering the upper cover member (44) on the upper opening of the case (43) which has a wide opening at the upper part, and for example, is composed of a resin molded article. Further, the ink absorber (42) is composed of a porous body such as a urethane foam body or the like, inserted in the cartridge main body (41) by being compressing, and then absorbs the ink.

[0193] The ink feeding orifice (45) for feeding the ink to the recording head (6) is formed on the bottom part of the case (43) of the cartridge main body (41), and the seal ring is fixed by being fit in the inner peripheral of the ink feeding orifice (45). Further, the atmosphere release orifice (47) is formed on the upper cover member (44). Then, on the cartridge main body (41), the cap member (50) is mounted for blocking the ink feeding orifice (45) in the pre-mounting condition and preventing the leak of the inner ink by deforming by compression the case (43) at treating the cartridge at mounting or during delivering, or by a pressure which is added to the board width side wall at vacuum packaging.

[0194] Further, as shown in FIG. 2, the atmosphere release orifice (47) adheres by paste the film shape seal member (55) having an oxygen permeation coefficient of 100 ml/m² or more on the upper cover member (44) to seal it. The seal member (55) is designed to be a size which seals the atmosphere release orifice (47) and also a plural number of grooves (48) which were formed around it. Further, when the cartridges (7) are packed under reduced pressure using a packaging member such as an aluminum laminate film or the like which has no permeation property, a gas occasionally dissolves in the ink at filling the ink, or because of the atmosphere which exists in a space (A) (refer to FIG. 3) which occurs between the ink absorber (42) and the cartridge main body (41). At this time, since the atmosphere release orifice (47) is sealed by the seal member (55) having an oxygen permeation coefficient of 100 ml/m² or more, air in the ink is discharged in a space having high vacuum between the packaging member out of the cartridge main body (41) through the seal member (55), the degree of degassing is improved.

[0195]FIG. 4 is a configuration example of a recording unit equipped with the recording liquid storing part which stored the recording liquid of the present invention and the head part for discharging the drops of the recording liquid. The recording is a serial type and the main part is composed of the ink jet head (33), the ink tank (49) which stores the recording liquid fed to the ink jet head (33), and the cover member (44) which closes the inside of the ink tank (49). A plural number of nozzles (32) are formed on the ink jet head (33). The recording liquid is introduced from the ink tank (49) to a common liquid chamber which is not illustrated, through the ink feeding tubes which are not illustrated, and discharged from the nozzles (32) in accordance with signals from the recording apparatus main body which are input by the electrodes (31). Such type recording unit is a structure which is often used for heads which can be produced at low cost, namely heads called thermal system or a bubble system which use thermal energy as a drive source.

[0196] The head part for discharging ink drops is illustrated showing the configuration example of FIG. 5. The head of the configuration example is a laminated structure which was obtained by laminating three silicon single crystal substrates (71), (72) and (73) to be connected. The use of single crystal silicon substrate is preferable for processing of preparing a thin vibration plate (a thickness of several μm) for discharging an ink, and preferable material when a gap of several μm is precisely formed at anode conjunction described later. Further, when the vibration plate is vibrated by acting electrostatic force, it is necessary to generate electrostatic force by impressing a voltage to the electrodes. Since silicon is a semiconductor and makes resistance low, it can replace the electrodes of the vibration plate side, and has advantages that the electrodes are not necessary to be individually provided at the vibration plate side, and the like.

[0197] The intermediary first substrate (71) has the concave part which constitutes the liquid chamber (76) in which the bottom wall is the vibration plate (75), the narrow grooves for the ink flow orifice which constitutes the fluid resistance part (77) which was provided at rear part of the concave part, and the concave part which constitutes the common ink cavity for feeding an ink to the liquid chamber (76).

[0198] The second substrate (72) of lower side which is connected with the under face of the first substrate (71) is a layer in which the silicon oxide film of (72 a) was provided on the single crystal silicon substrate of (72 b). The electrode (81) which is about the same shape as the vibration plate (75) is formed at the second substrate (72). The electrode (81) has the terminal part (83), and the whole part of the electrode (81) and the lead part of the electrode is covered with the insulation film (82) excluding the (electrode) terminal part (83) of the electrode. As the second substrate (72), a substrate using, for example, a Pyrex glass and the like other than silicon are known.

[0199] Then, the nozzle hole (74), the liquid chamber (76), the fluid resistance part (77) and the ink cavity (78) are constituted by the third substrate (73) at upside which is connected with the upper face of the first substrate (71). Then, the ink feeding orifice (91) which is connected with the ink cavity (78) is provided by drilling in the third substrate (73). The ink feeding orifice (91) is connected with an ink cartridge which is not illustrated, through connection pipes and the tubes which are not illustrated. As the third substrate (73), a substrate using, for example, a glass, nickel, a plastic, stainless and the like other than silicon is known.

[0200] In the inkjet head of the configuration example which utilizes electrostatic force which was constituted as described above, when a positive pulse voltage is impressed to the electrode (81) from the oscillation circuit (93), the surface of the electrode (81) is electrified to a plus electric potential, the lower face of the corresponding vibration plate (75) is electrified to a minus electric potential, and the vibration plate (75) is bent downward by the electrostatic suction action. When the impression of the pulse voltage to the electrode (81) is switched OFF, the bent vibration plate (75) restores its original posture, therefore the pressure in the liquid chamber (76) increases abruptly, the drops of ink liquid (92) is formed from the nozzle hole (74) and the discharge of the ink is carried out to a image receiving body which is not illustrated. Then, when the vibration plate (75) is bent again downward, the ink is fed in the liquid chamber (76) from the ink cavity (78) through the fluid resistance part (77). As described above, those switching the pulse voltage to ON/OFF and an alternate current and the like are applied to the oscillation circuit (93). When the recording is carried out, it is carried out by controlling the electric pulse which should be impressed to the electrodes (81) of the respective nozzle holes (74).

[0201] The ink of the present invention can suppress the elution of silicon and silicon oxide which are used for a printer having the above-mentioned configuration example, prevents problems such as the lowering of image quality caused by the fluctuation of the size of ink drops by lowering the design precision of a printer, the occurrence of discharge inferiority, and the trouble caused by the lowering of the connection strength of the conjunction part, and can prevent the clogging caused by the elution of silicon to the ink.
